Cd1Pd2Sn1
Cd1Pd2Sn1 is a semiconducting ternary intermetallic compound composed of cadmium, palladium, and tin, primarily studied for its potential in catalytic material research.
About Cd1Pd2Sn1
Cd1Pd2Sn1 is a specialized ternary intermetallic compound classified within the platinum-group alloy catalysts. Its electronic character is defined as semiconducting, distinguishing it from the purely metallic behavior often observed in similar palladium-based systems.
While it exhibits a complex structural landscape with numerous reported configurations, it is noted to exist above the thermodynamic hull. This suggests that the phase may be metastable under standard conditions, requiring specific synthetic pathways for stabilization in catalytic applications.
Key Properties
Cross-validated computational properties for Cd1Pd2Sn1, aggregated across 2 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
